CBS‘ The Big Bang Theory The Bachelor Party Corrosion TV Show Review. The Big Bang Theory: Season 9, Episode 3: The Bachelor Party Corrosion felt like a triumphant return of the funny factor. Sure, while the first two episodes of Season 9 balanced the funny and dramatic storylines exceptionally well, this episode was the first of the season to focus primarily on the laughs. When the guys decided to take Leonard on an impromptu bachelor party trip to Mexico, it quickly became apparent that things were not going to go as according to plan. Set up with an aging van and a limited knowledge of Mexico or basic vehicular repair experience, Leonard (Johnny Galecki), Sheldon (Jim Parsons), Raj (Kunal Nayyar), and Howard’s (Simon Hedberg) trip met a quick and hilarious end in the middle of the Mexican desert. Meanwhile, Penny (Kaley Cuoco), Bernadette (Melissa Rauch), and Amy’s (Mayim Bialik) take on a bachelorette party didn’t go as planned either. Despite Amy’s ludicrous attempt at baking phallic-shaped cookies, the gathering instead brought up the issues of Amy and Penny’s secrets that they were keeping from their loved ones back home.

Penny had not yet informed her parents of her marriage to Leonard, which resulted in heavy pressure and guilt from Amy and Bernadette. However, it quickly became apparent that Amy had yet to tell her mom about her and Sheldon’s split-up. The two tip-toed around the issue until ultimately Penny mustered up the courage to tell her father about the wedding, which needless to say, didn’t go how Bernadette and Amy had anticipated. Instead, Penny found out that her father had been keeping a secret of his own: her pet pig had been dead for months. In his eyes, there was no harm done, and he considered their mutual secret-keeping even. In Penny’s frustration, she then forced Amy to call her mother, and when Amy skirted around the issue to telling her mother about Sheldon, Penny took it upon herself to spill the beans. The hilariousness and ridiculousness of the confessions were a great breather from the frustrating, yet also hilarious mishaps that the guys were experiencing on the road.

As Sheldon expectedly persisted against their trip to Mexico, the guys did their best to convince him of the positives. However, a popped tire quickly flattened their expectations, and proved to be more than a quick fixer-upper for the group. Even though Howard knew how to change a tire, none of the hopeless travelers could figure out how to get the tire unscrewed off of the axle. The scientific debates, sidesplitting superhero references, and ensuing banter made this the most enjoyable part of the episode. We finally got to see the guys acting in the moment, instead of with the heavy burdens of guilt, remorse, and sadness in their ways. They were back to their old, normal selves, if only for a moment…and we loved every minute of it.

While The Bachelor Party Corrosion made sure to bring the laugh meter up, the overall story was fairly unimportant to the overall storyline. It was a great filler episode that is sure to be one of the comedic highlights of the season, but didn’t dabble too far into developing character arcs or setting up any future episodes. We still are curious to see if Leonard and Penny’s marriage is officially sailing smoothly, and we definitely want to see where Sheldon and Amy’s rocky path is headed. But for now we will have to wait and see. The biggest question remains: How will Sheldon handle Leonard’s leaving of the apartment to live with Penny? Will he react the way we are all expecting, in one of his classic temper tantrums? Or will he react positively? Only time will tell, but from the sound of things, that’s one storyline our characters will be addressing very soon.
